T'ogall'w'hom it may concern Q Bei't-knoii-"n that I, CnAnLnsH. LMv'roN, eitizen'of the United States, residing at Tor'ringto'n, county of Litchfield, State of "Connecticut, have invented an Improvement Y in Molds for lCasting,r Ingots,.o'f which the following Ais a'rspecification.

"This invention relates more especially to the type of molds used lfor casting ingots and has for its object to greatly reduce the cost of producing;rv ingots. This reduction in "cost I'ell'ect by the'zuse of m-y novel molds which are"niade in four p'arts'instead of wtwo, two of the parts being permanent and 16 't o renewable." For convenience in description, AI will terni the renewable parts mold i1 1ii'ibers and the permanent parts container members. The mold 'men'i'bers are plain il stings that match together and cost con- 20L` lei'ably leSs`tl ian half` `the' cost of mold "members-as ordinarilyconstructed. In my inovel structure, the foot of the mold is upon "one' ofthe container members and the drilling and other machine work for fitting the locking means is .all upon the container members, which may be used continuously lfor an` almost unlimited length of time. `In twfo-part molds, the parts are necessarily ::'r` nade heavy and when tliei'nold is worn out 30,1"the clamping means is discarded with it and f becomes a, total loss'. The mold members of i mynovel mold are made about one-half tl .weight of ordinary two-part moli/l' bers, which effects an iniportant/sa/vifg. l find furthermore that owing tothe'relative "thinness of'my novel inold members, they last very much longer thanthe lundi heavier two-lmrt inolds, thus eifectingan additional saving :inf the cost (if producing ingots. 40; Tliis'for the reason that whenpouringtakes place, the inner surface ofA the mold members ...issubjected to intense heat, which does not .penctratethe' mold nwmbersqiiiclclyowing)Y to their thickness. The. resultV is that the mold, members crack very readily, as the heat of the inner side of the members is L soinuch greater than that of the outer side, and owing?r to this uneven heating alternati n;r w-ith V cooling Vthereof, the mold lniemfbers inavddition to cracking are caused to .'.stretch andA bulge so vthat they deteriorate very rapidly. VIn my novel. foar-part molds,

' member l() com-prises the ba( the mold members are made relatively light and thin and the heat from the molten metal penetrates them quickly, so' that the inner and outer sides of the mold members are heated more uniformly. This enables me to run a much greater num-ber of heats without surface cracking.
